Özet:

Transportation infrastructure is one of the most important factors that demonstrate the development level of a country. For this reason, it is observed that the cities with a high quality of life index, have advanced public transportation systems. Today, parallel to the increase in urban population, human mobility has increased and public transportation has become one of the most important elements of urban life. The high cost of urban public transportation investments has led decision makers to focus on performance-enhancing studies that do not require additional investments and will enable more efficient use of existing fleets, rather than focusing on new investments in short term. In this study, a mixed integer programming model has been developed to increase the efficiency of the existing system by examining the urban transportation system of the Erzurum Metropolitan Municipality, consisting of 29 bus routes in total. With developed model, it has been aimed to minimize the number of buses, serving on the lines, and the idle capacity, considering the passenger demands on weekdays and weekends, bus types, and capacities. As a result of the study, alternative scenarios and solutions have been produced by making changes in the mathematical model according to the experiences and demands of the decision makers.
